  • Tris(N-carbalkoxylaminomethyl)phosphines
    Patent number: 4204072
    Abstract: The title compounds, having the formula (RO.sub.2 CNHCH.sub.2).sub.3 P, are prepared by reacting a quaternary phosphonium salt, having the formula (RO.sub.2 CNHCH.sub.2).sub.4 P.sup.+ X.sup.-, with a base, preferably one that is capable of reacting with and thereby inactivating the by-product formaldehyde or formaldehyde derivative. The products are useful as intermediates for the preparation of finishing agents that impart flame retardant properties to cotton fabrics.
